STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 632,839, dated September 12, 1899.

Application filed January 3,1898- Sorial No. 665,369. (No model.)

To aZZ whom it may concern:

Be it known that I, STILES LINDERSMITH, a citizen of the United States, residing at the city of Faribault, in the county of Rice and State of Minnesota, have invented certain new and useful Improvements in SteamJlo tor Road-Vehicles, of which the following is a specification.

My invention relates to improvements in steam-motor road-vehicles, and more particularly to an improved steam-boiler for the same which will generate steam under ahigh pressure and in which is provided an improved form of construction by which the boiler may be readily taken apart.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of my improved boiler shown attached to a four-wheeled steam-motor roadvehicle. Fig. 2' is a detail front elevation of the boiler shown fastened to the vehicle and partly in cross-section. Fig. 3 is aplan view of Fig. 2. Fig. 4t is a vertical cross-section of one of the boilers shown detached from the casing and pipe connections. Fig. 5 is a diagrammatic view of the steam-generatingapparatus, showing the fuel and water tanks and pipe connect-ions.

In the drawings let A represent a fourwheeled vehicle comprising the box portion 2, springs 3, wheels 4 and 5, axles 6 and 7, framework O, and steam-engine B, having connections 8 and 40, and the steam-pipe 9, which leads to and connects with myimproved boiler D. The boiler D is composed of a series of boilers F, which are mounted upon the framecasing 10, which is fastened upon the dash 11 of box 2 of the vehicle by means of screws 12, which fasten through lips 13, formed on the sides of said casing. Each of the boilers F is composed of the drums 14, as shown in Fig. at, end plates 15 and 16, which are fastened by means of bolts 17, passing through the same, and held by means of nuts 18, which when turned draw the end plates against the casing 14c and flue-pipes 19. The casing 14 and flue-pipes 19 are recessed into the end plates, which are provided with annularshaped recess-grooves 21, in which the steampacking 20 is placed. Thus by tightening the nuts 18 the end plates are drawn against the casing and flue-pipes, producing steam-tight joints. To the lower end plate 16 is fastened, by-means of screw-threads 22, the combustion-chamber 23, which in turn is mounted upon the outer casing 10 by means of bolts and nuts 24. and 25, and gasolene-burner 26 is located in chamber 23, and its supply-pipe 27 connects to the same through opening 28, and the valve-handle 29 ofthe burner 26 passes through opening 30, which is of proper dimensions to admit air to the burnervalve when the device is in operation. An upper chamber 31 is provided for carrying off waste gases and smoke from the boiler, which is fastened to the end plate 15 by means of screw-threads 32 and connects with a series of said chambers 31 by means of pipes 33 and finally with outlet-pipe 34, which is located at one side of the vehicle. Thus the gases and smoke pass from the burner to the outer atmosphere. Tapped into the center of the end plate 15 is the steam-pipe 35, having opening 36, which leads through opening 37, formed in the end plate 15, and into the steamchamber 38, and also connects with the main steam-pipe 9. The valves 39 are inserted in each outlet-pipe, by which the passages in the respective pipes may be opened and closed, which enables the independent operation of each boiler as desired.

To prevent the heat from radiating from the boiler D, I preferably pack between the boilers F and the casing 10 asbestos 56 or other suitable non-heat-conducting material.

In the operation of my improved device water is fed through the valves as from the tank 44, which is fastened to the seat 48 of the vehicle by means of bolts 50, by turning the supply-valves 33, corresponding to the desired boilers to be operated, which are inserted in the water-supply pipes of the boilers. The corresponding gasolene-burner valves 47 are then opened, thus allowing the gasolene to enter from the supply tank 46, which is mounted upon the seat 49 by means of bolts 51, which allows the gasolene to pass through the pipe 45, which leads and connects with the burner supply-pipes 27. The corresponding outlet-steam valves 39 are then opened, which allows the steam as generated to enter the pipe of the main steam pipe 9. The heat from the burner when ignited passes from the heating-chamber through the flue pipes and into the smoke-chamber, from where it is conducted through the smoke-pipe 33 to the outer atmosphere.

When the device is in full operation, the water is fed into the boiler-pipe by means of the injector 42, which is tapped into the portion 41 of the pipe 9 and has connections through pipe 53, 52%, and 55 with the boiler D. Steam is fed'from the boiler by opening and closing the valve 52, which is inserted in the main steam-pipe 9.

Having described my invention, what I wish to secure by Letters Patent is' 1. In a device of the class described the combination of the flue-pipes and boiler-casing, which are respectively recessed into the end plates of the boiler; the rods or bolts for strapping the ends against said fines and casing, adapting the same to be held in place and easily taken apart for cleaning; the fuelchamber fastened to the lower end plate, which in turn is bolted to the boiler framework or outer casing; the smoke-chamber fastened to the upper end plate, having the smoke-pipe leading therefrom; the steampipe screwed into the upper end plate, passing through the smoke-chamber and out through the top thereof, which is adapted to be connected to the supply steam-pipe, all substantially as described.

2. The combination in a device of the class described of the battery-boiler, consisting of a series of boilers, each respectively composed of the flue-pipes and boiler-casing, which are recessed into end plates and fastened lengthwise by means of bolts; the smoke-chamber,

. fastened to the upper end plate, which is provided with the smoke-pipe, leading therefrom; the steam-pipe, fastened to the upper end plate, which passes through the smokechamber and connects with the steam-chamber, being adapted to lead from the boiler and connect with the main steam-pipe; the fuelchamber, rem ovably fastened to the lower end plate, for containing fuel-burner; the bolts for fastening the boiler to the outer framework, which are formed upon the lower edges of the fuel-chamber, and adapted to pass through the outer framework of the boiler= shell; the outer framework consisting of the casing which surrounds the boilers and the space between which and the boilers for con:

taining a poor heat-conducting material; said outer casing for containing said boilers between which and the boilers is the poor heatconducting material for insulating the boilers from the outer atmosphere, all substantially as described.
